UNITED STATES FLUID-FUEL BURNER.

Application filed November 17, 1924. Serial No. 750,279.

To all whom it may concern:

Be it known that 1, PETER Jonnsori, a

citizen of the United States, residin at 7 lec't and rom which it will flow backward- Seattle, in the county of King and tate of Washington, have invented a certain news and useful Improvement in Fluid-Fuel- Burners, of which the following is a specification. v

My invention relates to improvements in fluid fuel burners of the type used in domestic cooking stoves and the object of my invention is to provide a fluid fuel burner thatembodies means that yvill prevent the flooding of the interior or body portion of the burner and fire box of the stove with fluid fuel if such fuel is not in a gaseous state.

The, fluid fuel burners now in common lighted and burns causing the burner, fire box and flues to become coated withsoot and also causing a great amount of smoke while in my burner all of these objectionable features are eliminated by providinga fluid fuel conduit within the urner body ata sli ht upward incline with respect to the horizontal which conduit is also provided on its discharge end with a well or shallow receptacle arranged to catch the fluid fuel and prevent the same from being discharged into the burner body the angle at which the conduit being such that the fluid fuel will flow back into the ash pit of the stove.

j I accomplish the above .objects by devices illustrated in the accompanying drawin s, wherein igure 1 is a view in longitudinal section showing one form of burner having fuel Referring to the drawings throughout.

which like reference numerals indicate like parts, 5 designates a burner body which is herein shown to be of rectangular shape.

My invention consists in the provision within the burner body 5 of a fuel inlet conduit 6 which enters the burner body on PATENT OFFICE.

PETER JOHNSON, OF SEATTLE, GI'ON.

an upward inclination with respect to the horizontal and which terminates in means formm a well 8 in which oil maycolly along the conduit and out of the outer end thereof ,in'stead of being discharged within the bbdy of the'burner.

The means 7 forming'the well 8 that is illustrated in the drawings is in the nature of a T fitting connected with an extend-' ing crosswise of the conduit 6 in a horizon tal position and open at both ends and is provided acrossthe lower segmental portion of both ends with webs or dams 9 which cooperate in forming the well 8. It will be understood that the well forming member 7 and also the conduit 6 may be inte ral er if desired and may be varied in sha e to suit the requirements of the burner b0 y into which it is incorporated.

The outer end of the conduit 6 may terminate outside of the burner body in a suitable location, as in an open. cap 10, where a plentiful supply of air may be obtained.

The burner is provided with a gasifying pipe 11 7 connected therewith in any suit able manner so that it passes through the area that is heated by the flame when the same is in operation, the end or tip 11 of said pipe being arranged to project into the cap 10 and being disposed in alignment with the fuel con it 6 and forming a tip from which'a jet of fuel may be delivered into the conduit 6.

In the operation of my burner the fuel will be gasified in its travel through the pipe 11 and will issue from the tip 11 as a jet of gas which will be directed across the gap in the cap 10 and into the conduit pipe 6 after the fashion common to Bunsen burners.

If for any reason the oil is turned on too with the body portion of the burn-' HEISSUED quickly in primin the burner or the flame is extinguished w ile the burner is in o eration the liquid fuel instead of gas will be jetted into the pipe 6 and, unlessthe pipe 6 is rovided with means for disposing of this iquid fuel, the same will be ignited in the burner body and burn with smoke and soot that tends to clog up the burner tip.

If the fuel is turned on in my burner before the pipe 11 is heated sufficiently to glasify the same, liquid fuel will be emitted om the tip 11 into the Well 8 but will flow rearwardly along the pipe 6 and out into the ash pit of the stove or furnace in which the burner is disposed or into an receptacle that may be provided for catc in the same thus avoiding burning the liqui fuel in a non-gaseous state within the burner body.

The foregoing description and accompanying drawings clearly disclose what I now consider a preferred embodiment of my invention, but, it will be understood that this disclosure is merely illustrative and that such changes in the construction of the burner may be resorted to as are within the scope and spirit of the invention.

What I claim is:

1. In fuel inlet means for an oil burner the combination with an oil' burner body, of a fuel inlet conduit open at theouter end and arranged to extend into said burner body in upwardly inclined relation to the horizontal, and a T fitting forming a well at the inner'end of said conduit, said T fitting having outlet openings located above the level of the hi hest point of the bottom of said conduit W ereby liquid will not be discharged from said outlet openin but will flow by gravity outwardly throug said conduit.

2. In a fluid fuel burner a burner bod a fuel inlet pipe extending into said b0 y and inclined upward relative to the horizontal the outer end of said inlet pi e being open, means for delivering a jet of uel into the outer end of said inlet pipe, and a horizontally arranged T fitting on the inner end of said fuel inlet pi e, the ends of said T fitting being partia 1y closed by segmental webs that extend across the bottoms of the same and form, within said T fitting, a well from which liquid will flow outwardly through said inlet pipe before it overflows said webs.

In witness whereof, I hereunto subscribe my name this 12th day of November, A. D., 1924. I

7 PETER JOHNSON.
